由苯骈咪唑-5-羧酸构筑的Cd(Ⅱ)配合物的水热合成、晶体结构和荧光性质(英文)

Synthesis,Crystal Structure and Luminescence Property of A Cd(Ⅱ) Complex with Benzimidazole-5-carboxylic Acid

通过水热合成的方法得到1个由苯骈咪唑-5-羧酸(HL)配体构筑的Cd髤配合物[Cd(L)2(H2O)]n。在配合物中,镉中心为变形的八面体配位构型。每个配体连接着2个镉原子,每个镉原子通过4个配体相互连接,在bc面上形成以平行四边形为基本结构单元的二维层状结构,层与层之间通过N-H…O和O-H…O氢键连接形成三维超分子网络结构。此外,我们还研究和讨论了配合物的固态荧光性质。

A Cd（Ⅱ） complex, [Cd（L）2（H2O）], （1）, based on benzimidazole-5-carboxylic acid （HL） ligand has been hydrothermally synthesized. The Cd（Ⅱ） atoms have a distorted octahedron coordination geometry. Each L ligand links two Cd（Ⅱ） atoms and each Cd（Ⅱ） atom attaches to four L ligands to form a two-dimensional （2D） layer structure along bc plane, which consists of regular parallelograms, then yield a three-dimensional （31）） supramolecular network by N-H... O and O-H... O hydrogen bonds. The TGA and luminescence property in solid state of complex 1 have been further studied and discussed in this paper. CCDC： 722775.
